I understand the rationale but I don't see a way that Catton goes #6 at the actual draft. Obviously there are always surprises, but Lindstrom has been projected top 5-8 for the last six months, Iginla has shot up like crazy over the last month, I have to imagine both of those guys go before Catton for sure, let alone the unicorn in Silayev. Parekh, maybe, too.
Thing is, Lindstrom has been injured for parts of the last half of the season, and when he has played has been inconsistent. Iginla has come one really well at the end of the season, but before that was well back. Catton has been superb and extremely productive all season long(most points of any draft eligible CHL'er), and it turns out he was playing injured at the end of the season. Points aren't everything, but they are a thing. Catton had 116, Iginla 84, Lindstrom 46 - all in the same league.
The only reason to take the other two over Catton is because of their size and strength - the good'ol Charlie Stramel rationale. While you shouldn't ignore size and strength, remember that Catton is at least 1.5-2" taller and a better skater than Perfetti and Rossi were. The guy is not tiny.
The combine results for Catton will be interesting. I have seen as high as 6', as low as 5'10". Most sites have him at 5'11.
I am always wary of picking prospects who dominated lesser leagues because of the size and strength. Unless they are absolute monsters, they usually get taken down a peg or two once they get to the NHL and they run into guys like Foligno, Wilson, and the like. Conversely, late maturers physically like Catton can usually transform their bodies given time, good nutrition, and a pro workout schedule.
